Initial bug report could be found here [1]. Comments 14 and onward are
probably helpful. To reproduce the issue I have downloaded "assets"
from [2] and recreated test environment as found in autoinst-log.txt [3].
Search for qemu-img and qemu-system-aarch64 in the log above. Login
credentials for the images could be found by searching for "password"
in the same file.

Regards,
Ivan
